Hirobo HI0404322 Tail Pitch Plate Mounting Boss for Eagle/Freya/EX/SX  [HI0404322]

What the tail boss does

This Hirobo HI0404322 tail pitch plate boss is provided as a service replacement part for the tail pitch assembly on the listed models. It acts as the mount where the pitch plate connects to the tail linkage, establishing the pivot and fixed location for the pitch control path.

Supplied for ease of installation into the tail stack, the component preserves pitch plate alignment, reduces lateral slack in linkage joints, and helps keep consistent pitch geometry for improved control feel. The note is intended for modelers doing regular upkeep, part swaps, or small control refinements.

Installation notes: check existing linkage geometry before removing the old boss, use the model maker's recommended torque settings for screws, and verify full, unobstructed pitch travel after installation. Make conservative adjustments and validate with hover tests before pushing control limits.
